A federal judge has again sent back to Cook County Circuit Court a class action dispute about how many credit card digits appear on restaurant receipts, saying, while federal courts have been clear the case is a non-starter, Illinois state courts have yet to answer.

A woman who claimed she overpaid for her sausage burrito meal at a McDonald’s restaurant in The Loop has become the second plaintiff asking Cook County courts to make McDonald’s and a local McDonald’s franchisee pay for charging a few cents more the meal as a bundled “Extra Value Meal,” rather than a la carte.

Roti Restaurants, a Chicago-based chain specializing in fast, fresh Mediterranean-style food, has been served with a class action lawsuit, alleging the chain prints too many digits from its customers’ credit and debit cards on receipts.
